To perform front terminal open-circuit calibration.
:cal:prot:dc:step2
None
:STEP2 performs the open-circuit calibration step in the comprehensive
calibration procedure. Disconnect all cables and accessories from the input
jacks before sending this command.
:CAL:PROT:DC:STEP2
To program the +10V comprehensive calibration step.
:cal:prot:dc:step3 <Cal_voltage>
<Cal_voltage> = 9 to 11 [V]
:STEP3 programs the +10V DC comprehensive calibration step. The
allowable range of the calibration voltage parameter is from 9 to 11, but 10
is recommended for best results.
:CAL:PROT:DC:STEP3 10
To program the -10V DC comprehensive calibration step.
:cal:prot:dc:step4 <Cal_voltage>
<Cal_voltage> = -9 to -11 [V]
:STEP4 programs the -10V DC comprehensive calibration step. The allow-
able range of the calibration voltage parameter is from -9 to -11, but -10 is
recommended for best results.
:CAL:PROT:DC:STEP4 -10
Calibration Reference
